Anthony Davis is 21 years old and is averaging 23.9 ppg, 10.5 rpg, 2.9 bpg, 1.6 spg, and 1.6 apg. He is shooting 57.6% from 2 point range and over 80% from the foul line. If that doesn't say superstar I don't know what does.
Demarcus COusins is 24 years old and is averaging 23.5 ppg, 12.3 rpg, 1.6 bpg, 2.9 apg, and 1.1 spg. He is shooting a respectable 79.7% from the line, though his 49% from 2 is a bit light for a center. If that doesn't say superstar I don't know what does.
Steph Curry is 26 years old and is averaging 22.9 ppg, 8.0 apg, 5.1 rpg, and 2.2 spg and an obscene 57.6% form 2 for a guard, 39.2% from 3, and 92.3% from the line (30th best all time if he finishes there). Again, superstar numbers.
John Wall is 24 years old and is averaging 17.4 ppg, 10.4 apg, 4.5 rpg, and 2.1 spg with respectable shooting from a PG. As PG's guard, he is projecting to go down as a top 5 PG in the history of the game.
Speaking of top 5 PG's in the history of the game, Chris Paul is still performing at a superstar level and at 29 likely has 3ish prime years left before he starts his decline. And we haven't even discussed James, Durant, Harden, Griffin, Lillard, Aldridge, Rose, George, etc.
The premise of this thread is just silly.
